To all whom/ i may concern,.-

Be it known that I, DUNCAN A. MCTAVISH, a citizen of the United States,residing at fest Bay City, in the county of Bay and State ofMichigan,have invented certain new and useful Improvements in lVagon-Jacks, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to improvements in wagon-jacks; and it consistsin the combination, arrangement, and construction of the parts 'with theobject of producing a-device for lifting wagons which can be used by aper1 son standing at the outer side of the wheel, whereby the trouble ofpassing behind the wheel for adjusting' and operating the jack isavoided.

Another object of the invention is to construct a light and durablewagon-j ack which, while being effective and easy of operation, is atthe same time cheap and simple in its adjustment and operation.

My improved wagon-jack is illustrated in the accompanying drawings, inwhich the same letters of reference will be found indicating the sameparts or elements throughout the several views.

Figure l represents a lateral side View in elevation of my improvedwagon-jack, showing the parts in position when lifting a wheel and withthe axle in transverse section. Fig. 2 isa rear side View of the same.Fig. 3 is a top or plan view of the same. Fig. 4: is a section of Fig.l, taken at 0c.

a represents a foot-piece which rests upon the floor or ground, and b isavertical standard with its lower end permanently secured to thefoot-piece and to the upper end of the standard is permanentlysecuredthe front and rearwardly-extending arms c and CZ, the outerportions of the arms being also curved upwardly. The arm c is providedupon one side with ratchet teeth or notches e.

fis a lever with one end g pivoted to the upper end of the arm d by abolt h, the end being provided with a fork which extends on both sidesof the arm, while the opposite end of the lever, extending to a suitabledistance beyond and beside the arm c, is provided with a handle t',while the portion j, passing the arm c, is arranged to engage with theteeth e, and this part y' is provided with a guard-piece 7c, whichextends across the opposite side of the arm, leaving a sufficientopening Z between the arm and the guard to allow the lever to pass thenotches or teeth e, when required. The central portion of the leverbetween the arms c and d is provided with an elongated vertical openingn, and through this opening 6o is passed the upper end portieri of avertical bar o, which is provided with a series of openings p, and a pinq is passed through suitable openings in the lever, and also through oneof the openingsp for retaining the parts in position. The lower portionr of the bar is extended downwardly beside the standard b, and isprovidedon its lower end with a transverse lifting-piece s, having avertical opening t, through which passes the 'stand- 7o ard, the openingbeing arranged so that the piece will easily move upon the standard, butstill be retained against lateral movement.

In operating the device the lever is released from the notches e andallowed to move down-` ward until the inner side of the guard lc restsupon the curve of the arm. The vertical bar 0 is then adjusted to bringthe lifting-pieces beneath the axle carrying the Wheel to be removed oroperated upon. The pin q is then 8o passed through the required openingp, and the handlet is then raised, which also lifts the vertical bar andthe piece s and the axle to the requiredA height. The lever is thenmoved laterally andrthe portion j engaged with the proper notch e, andthe parts will then be retained for manipulating the wheel, as desired.

It will be noticed that the construction shown allows the parts to beoperated by 9ol reaching over the wheel, as the adjustingpin q may bemanipulated for adjusting the lifting-piece, as also may the lever beoperated by raising or lowering the axle with great ease and rapidity bythe workman standing upon the front side of the wheel, so that n it isnot necessary to pass behind the wheel in order to operate the jack,and, also, the jaclrmay be placed between the axles, and

then after operating upon one axle the jack roe` may be moved directlyback and engaged with the other ax'lewithout removing the j ack frombehind the Wheels, whereby a great saving of time and laborisaccomplished, besides making a device which is light and easily operatedand which can be sold for a loW price.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination, in a Wagon-jack, of the vertical standard having uponits lower end a foot-piece and provided upon its upper end withoutwardly and upwardly extending arms c and d, the arm c being providedwith ratchetteeth e on its side face, a lever with one end pivoted tothe said arm d and with its opposite end extending beyond the arm c anden-
